How long does exterior paint last in Brisbane?

Most exteriors last eight to twelve years here. Here is what shortens that, and what you can do about it.

The short answer

A well-prepared exterior in Brisbane usually lasts eight to twelve years. West and north walls wear fastest because they take the afternoon sun.

What shortens it

Paint applied over dust, chalk or salt lets go early. So does paint on timber that was damp, and a single heavy coat instead of two proper ones.

What helps

Wash the house every year or two, keep gardens and sprinklers off the walls, and touch up chips before water gets behind them.
